Marked by sameness and a lack of originality; mass-produced. Often used to describe suburban housing developments where all of the houses are based on the same blueprints and are differentiated only by their color.

I wouldn't live in one of those ugly cookie-cutter houses for a million dollars.

A female adolescent, usually between the age of 15 and 25 (but most notorious in High Schools), whom bears an almost uniformic exterior appearance consisting of a basic fashion formula designed to include high visual contrast:
-artificially tan skin (usually orange-y)
-streaked or bleach blonde hair, or very dark hair
-possesses blue or light-colored eyes, indicating a recessive gene or colored contacts; can also be very dark-colored eyes
-bleached teeth
-wears light-colored clothes to pronounce contrast
-is of white ethnicity (in most cases)
-wears thick makeup
-wears form-fitting pants that show detailed form of lower body
-is able to make the f__king annoying "click-clack" sound with chewing gum

If there were no cookie-cutters in my school then I could've sworn that I saw the same person twenty times today in random locations.

People who all act, look, and dress the same. They're usually very mean, popular girls who think they're the best out of everyone and disrespect anyone who isn't their friend. The easiest way to recognize them are if they post Vines of themselves twerking, all look the same, only listen to modern songs and won't let anyone in the room listen to what the want without complaining, and usually have about one to five boyfriends in one week. Most people don't like the Cookie-Cutter breed because they are by far one of the most aggravating types of people other than jocks. They never think about the feelings of other people except their friend's or their's and are mostly the reason that people never do anything fun in any classes.

The opposite of a Cookie-Cutter is a Misfit, who are usually tormented by Cookie-Cutters.
